TDK has introduced 7.5kW DSP-controlled programmable power supplies that are 1U size for rack mounting.
Part of the company’s Genesys+ series of PSUs, there are six models:
0 – 20V 375A, 0 – 40V 188A, 0 – 100V 75A, 0 – 150V 50A, 0 – 600V 12.5A and 0 – 1.5kV 5A.
The units can operate in constant-current, constant-voltage, or constant-power limit modes, and offer internal resistance simulation.
For more current, up to 12 units can be paralleled. “A multiple unit system to achieve a dynamic response and ripple and noise performance comparable to that of a single power supply,” according to the company. “Simply connect a single data link cable between units, and connect the dc outputs in parallel. The command and auxiliary units auto-configure and set their parameters accordingly.”
Each of these models can be obtained with a three-phase 170 to 265Vac input, or a three-phase 342 to 528Vac input. Active power factor correction is included, and peak operating efficiency amongst the series is 92%.
Programming and monitoring is either by front panel controls or remotely via digital (LAN (LXI 1.5), USB 2.0 and RS232/485) or analogue (isolated 0-5V and 0-10V). Optional interfaces include EtherCAT, Modbus-TCP or GPIB (IEEE488.2).
An LCD is included as a user-interface when setting voltage and current. Arbitrary waveform test profiles of up to 100 steps can be generated, stored in four memories, then activated by commands from the front panel controls or communication ports.
Safety features include safe/auto re-start and last setting memory.
An accompanying software package has drivers, a waveform creator and a virtual front panel GUI.
Dimensions are 423mm wide, 486.5mm deep, 43.6mm high and <8.5kg. Cooling is via variable speed fans controlled with respect to ambient temperature and the output load.
Safety certification is to IEC/EN/UL 61010-1 with CE and UKCA marking to the Low Voltage, EMC and RoHS Directives.
The series is also compliant with IEC/EN 61204-3 for conducted and radiated EMI and EMC immunity.
Warranty is five years.
Applications are foreseen in electric and hybrid vehicle testing, research, semiconductor fabrication, battery manufacturing and renewable energy.
